I've given up on wearing my glasses with any of my cameras: I have myopia in both eyes and astigmatism in my left eye, but since it's my right eye that I use to peep through the viewfinder, I just go glasses-less and use auto-focus (Nikon N80) or figure it out with my rangefinders (Bessa R and Leica IIIc), and do pretty well.

With best regards.
